The Edelbrock Performer intake manifold for small-block Chevrolet (1955–1986) uses a patented dual‑plane, low‑rise design to broaden torque from idle through about 5,500 rpm, improving throttle response for street use. This polished Performer version provides a classic shine while accepting air‑conditioning and alternator accessories. It fits a wide range of SBC engines but excludes 1987+ cast iron Bowtie heads.
